Difference between HttpServeltRequest.getAttribute() and getParameter()


  • getParameter() returns http request parameters. Those passed from the client to the server. For example http://site.com/servlet?parameter=1. Can only return String
  • getAttribute() is for server-side usage only - you fill the request with attributes that you can use within the same request. For example - you set an attribute in a servlet, and read it from a JSP. Can be used for any object, not just string.
